Help with family holiday - warm sandy beach with swimmable sea

Hello, I'm a bit overwhelmed with searching for the perfect holiday destination..

We are a family of 3 and have 10y old kid. We're looking for a resort with private sandy beach which we can swim in. We don't want windy or one with loads of seaweed. We're spending a significant amount of our money on the holiday and really don't want it to go wrong

I am considering to go to TUI blue Sarigerme for 5 nights and 2 nights in Ölüdeniz. But heard some missed reviews on the sea in sarigerme.

Open to any other area too. We will be traveling from Dublin

Thanks
